Efficacy and safety of combining short-course neoadjuvant chemoradiotherapy with envafolimab in locally advanced rectal cancer patients with microsatellite stability: A phase II PRECAM experimental study.

Conventional neoadjuvant chemoradiotherapy (nCRT) yields a pathologic complete response (pCR) rate of 15%-30% for locally advanced rectal cancer (LARC). This study ventures to shift this paradigm by incorporating short-course nCRT with immunotherapy, specifically Envafolimab, to achieve improved treatment efficacy and possibly redefine the standard of care for LARC. The PRECAM study is a prospective, single-arm, phase 2 clinical trial for LARC in patients with microsatellite stable (MSS) tumors. Participants received short-course radiotherapy (25Gy/5f), followed by two cycles of CAPEOX chemotherapy and six weekly doses of Envafolimab, a PD-L1 antibody, before total mesorectal excision surgery. The primary endpoint was the pCR rate. From April to December 2022, 34 patients were enrolled, of whom 32 completed the study, each diagnosed with an MSS rectal adenocarcinoma. All patients underwent preoperative CRT combined with Envafolimab. Remarkably, a pCR rate of 62.5% (20/32) was attained, and a significant pathologic response rate of 75% (24/32) was achieved. Additionally, 21 of 32 participants achieved a neoadjuvant rectal (NAR) score below 8, suggesting an effective treatment response. Common adverse events included tenesmus (78.1%), diarrhea (62.5%), and leukocyte decrease (40.6%). Two Grade 3 adverse events were noted, one related to liver function abnormality and the other to a decrease in platelet count. Surgical procedures were performed in all cases, with minor complications, including ileus, infections, and anastomotic leakage. As of this report, there have been no reported cases of recurrence or death during the follow-up period, ranging from 12 to 20 months. In LARC patients exhibiting MSS tumors, combining short-course nCRT with Envafolimab demonstrated favorable efficacy, leading to a significant pCR rate. Minor adverse effects and surgical complications were observed. These preliminary but promising results underscore the potential of this approach and call for further exploration and validation through a randomized controlled trial.

Preliminary Clinical and Radiological Outcomes of the "No-Punch" Decompression Techniques for Unilateral Biportal Endoscopic Spine Surgery.

To avoid the most offending surgical instrument for dural tears, we develop a "no-punch" decompression technique for unilateral biportal endoscopic (UBE) spine surgery. This retrospective study enrolled 68 consecutive patients with degenerative lumbar spinal stenosis segments. The treatment results were evaluated using the visual analogue scale (VAS) for low back and leg pain, the Japanese Orthopaedic Association (JOA) scores, and the Oswestry Disability Index (ODI). Radiological outcomes were evaluated using the preoperative and postoperative magnetic resonance imaging. This study included 36 male and 32 female patients who received 109 segments of decompression, with an average age of 68.7 (37-90 years). The average operation time was 52.2 minutes. The average hospital stay was 3.1 days. There were no dural tears but 3 minor surgical complications, all treated conservatively. The VAS for low back and leg pain improved from 4.6 and 7.0 to 0.8 and 1.2. The JOA score improved from 16.2 to 26.8, with an improvement rate of 82.0%. The ODI improved from 50.1 to 18.7. All these improvements were statistically significant. The cross-sectional dural area improved from 61.1 to 151.3 mm2, with an average increase of 90.2 mm2 and 205.3%. 87.1% of the ipsilateral facet joints and 84.7% of the contralateral facet joints were preserved. In 61% of the decompressed segments, the ipsilateral facet joints were preserved better than the contralateral facet joints. The UBE "no-punch" decompression technique effectively avoids the dural tears. It provides effective neural decompression, excellent facet joint preservation, and good treatment outcomes.

Local Flaps in Breast-Conserving Surgery in Early Breast Cancer Patients: Armamentarium for Breast Surgeon.

To describe the technique and outcome of local perforator arteries advancement flap in breast-conserving surgeries (BCS) in patient of early breast cancer as our initial experience and review of literature on it. Patients who underwent (BCS) with local perforator artery flap reconstruction were reviewed in terms of their clinical, surgical, and post-operative follow-up details after taking written and informed consent. We have described 4 patients of early breast cancer out of which one patient was post-NACT while 3 were for upfront BCS. We have performed LICAP in 2 patients, AICAP in 1 patient, and IMAP in one patient, depending on the location of primary tumors. None of the patients had any major or minor surgical complications in the post-operative period and drains were removed on post-operative day 2. All patients received post-operative radiotherapy and tolerated well without any loco-regional complications. Patients are in routine follow-up with cosmetic satisfaction without any local recurrence over 1year. The main advantages of pedicled perforator flaps are well-vascularized tissue, spares underlying muscle leading to lesser donor site morbidity like muscle function and seroma formation, easily reach the breast area with good match in terms of skin and subcutaneous tissue, faster recovery, and shorter learning curve in comparison to free flaps. Knowledge and skill about these flaps will help surgeon to give better surgical outcomes and satisfaction to patients.

Endonasal Endoscopic Optic Canal Decompression for Nontraumatic Optic Neuropathy: Long-Term Visual Outcomes in 36 Patients

Background: The management of compressive optic neuropathy (CON) arising from nontraumatic compression of the optic nerve within the optic canal (OC) remains a topic of controversy. In this study, our aim was to assess the effectiveness and safety of endonasal endoscopic optic nerve decompression (EEOND). In addition, we conducted an analysis of prognostic factors that could potentially influence visual outcomes. Methods: This retrospective cohort study was conducted between January 2015 and December 2021, involving adult patients (age > 18) diagnosed with CON and treated with EEOND at our specialized skull base expert center. The study evaluated the impact of surgery on visual acuity (VA), mean deficit (MD), and foveal threshold (FT) of the visual field (VF). These parameters were assessed preoperatively and at 3- and 12-month postoperative follow-ups. The relationship between clinical variables and the differences in postoperative to preoperative VA, MD, and FT of the visual field was analyzed through univariate and multivariate approaches. Results: Thirty-six patients (38 eyes) were included, with a mean age of 52 (±12) years, and a female predominance (78%). The mean ophthalmologic follow-up duration was 38 (±32) months. At the 12-month follow-up, 39% of the patients exhibited a VA improvement of ≥0.2 LogMAR. Partial VF improvement (MD improvement ≥25%) was observed in 55% of the patients, whereas 19% experienced complete recovery. In multivariate analysis, the presence of a type 4 OC was identified as the sole negative prognostic factor for visual improvement (VA and VF) at 12 months. Six patients (17%) encountered minor surgical complications, all of which were managed conservatively and had no impact on visual outcomes. Conclusions: Our study demonstrates that EEOND is a safe and effective procedure, even in cases of severe and long-lasting CON caused by nontraumatic compression of the optic nerve at the level of the OC.

Outcomes of Head and Neck Microvascular Free Tissue Transfer for Advanced Cutaneous Squamous Cell Carcinoma: A Comparison of Solid Organ Transplant Recipients to Nontransplant Patients

BackgroundPatients with solid organ transplant (SOT) are at increased risk of developing aggressive cutaneous malignancies due to their immunosuppression, particularly cutaneous squamous cell carcinoma PurposeThere is limited data regarding solid organ transplant patients with locally advanced cutaneous squamous cell carcinoma (cSCC) requiring radical surgery and microvascular free tissue transfer (MVFTT). Our objectives were to characterize outcomes in SOT patients and compare them with a non-SOT cohort. Study DesignThis is a retrospective cohort study of patients undergoing MVFTT for advanced cSCC of the head and neck between January 2016 and May 2020 at a tertiary referral center. Patients who underwent MVFTT as part of curative intent surgery for advanced cSCC during the study were considered for inclusion. Exclusion criteria included distant metastasis, palliative intent treatment, age less than 18 years, and lip primaries. PredictorThe predictor variable was SOT status. A cohort of non-SOT patients was matched to the SOT cohort based on age, smoking status, tumor stage, and defect size. Main outcome variablesThe primary reconstructive outcome was the major surgical complications and secondary outcome measures included major medical complications and minor surgical complications. The primary oncologic outcome was overall survival and the secondary outcome was disease-specific survival. The primary predictor was transplant status. CovariatesCovariates included patient comorbidities, prior treatment, tumor stage, type of reconstruction, pathologic findings, and adjuvant therapy. AnalysisContinuous and categorical variables were compared using Student’s T test and Fisher’s exact test. Survival was calculated using the Kaplan-Meier method and differences in survival between groups were calculated using the log-rank test. Statistical significance was set a priori at p ≤ 0.05 ResultsFourteen SOT and 14 matched non-SOT patients met inclusion criteria. There was not a statistically significant difference in the rate of major surgical complications (7% vs 7%, p = 0.74) between the SOT and non-SOT cohorts. Rates of minor (21% vs 43%, p = 0.26) wound complications and medical complications (0% vs 14%, p =0.24) were also similar between the SOT and non-SOT cohorts. Locoregional recurrences and distant metastasis were more common for SOT patients, though this was not statistically significant. Overall survival was significantly worse for SOT patients (21.7 vs 31.0 months, p = 0.04), though there was not a significant difference in disease-free survival (9.8 vs 31.0 months, p = 0.17). Conclusions and RelevanceMVFTT in the management of SOT patients with locally advanced head and neck cSCC demonstrates similar complication rates with non-SOT patients. While survival and oncologic outcomes are worse in the SOT cohort, aggressive surgical intervention with MVFTT can be performed with comparable complication rates to patients without a history of SOT.

Management of Persistent Syringomyelia in Patients Operated for Chiari Malformation Type 1

The treatment of persistent syringomyelia associated with Chiari malformation type 1 (CM1) is unclear. This study aims to evaluate the clinical and radiologic outcomes of syringo-subarachnoid shunt (SSS) as a treatment for persistent syringomyelia following posterior fossa decompression (PFD) for CM1. Forty-nine cases treated for CM1 associated syringomyelia at a single center were analyzed, 17 of them undergoing reoperation due to persistent syrinx formation. The patients' demographic data, neurologic presentations, and radiologic results were analyzed, including cerebellar herniation, posterior fossa volume, the level at which the syrinx started and finished, the size and diameter of the syrinx. Seventeen patients underwent SSS placement, with 1 minor surgical complication (a cerebrospinal fluid leak) occurring and requiring revision. No morbidity or mortality was observed. Among these 17 reoperated patients, partial or complete resorption of the syrinx was observed in all cases. The results suggest that if the syrinx diameter is >10 mm at its thickest point, extends for more than 10 vertebrae, and starts from the upper cervical region and extends to the upper thoracic region, the syrinx may not regress after the first surgery and potentially predicting the need for a second operation before PFD. SSS placement for persistent syrinx following PFD for CM1 is a safe and effective surgical treatment method. These criteria may also help predict the need for a second surgery and the overall disease outcome for both the surgeon and patient.

An Innovative and Highly Efficient Single-Port Endoscopic Nipple-/Skin-Sparing Mastectomy and Dual-Plane Direct-to-Implant Breast Reconstruction: A Prospective Study from a Single Institution.

The difficulty in creating and maintaining a stable workspace of the breast makes endoscopic nipple-/skin-spring mastectomy (E-N/SSM) develop slowly. This study aims to report the preliminary results of a novel endoscopic technique for N/SSM followed by dual-plane direct-to-implant (DP-DTI) breast reconstruction. A prospectively maintained database was reviewed that included patients who underwent single-axillary-incision E-N/SSM and DP-DTI breast reconstruction from September 2020 to April 2021 at a single institution by three surgeons. The data were collected prospectively and analyzed to determine the efficacy, feasibility, safety, and esthetic results of the operation, as well asquality of life (QoL). During the study period, a total of 68 E-N/SSM and DP-DTI reconstruction procedures through a single axillary incision were performed in 63 female patients. Among all the procedures, the majority were performed for grade 1-3 ptotic breasts (n =46, 73.0%). During the median follow-up of 26.5 months, themajor and minor surgical complication rates were 1.6% (1/63) and 9.5% (6/63), respectively. The cosmetic complication rate was 14.3%. One patient suffered local recurrence 4 months postoperation. The average scores in patient-reported outcomes at 2 years postoperation of satisfaction with breast (66.57), psychosocial well-being (75.93) and sexual well-being (56.29) were not significantly different compared with the baseline, except for physical well-being: chest (69.85). The proposed procedure for E-N/SSM and DP-DTI breast reconstruction is feasible, time-saving and safe with good outcomes in terms of cosmetic results and QoL and expands the indications of DTI reconstruction to ptotic breasts, making it easier to popularize.

Bilateral simultaneous cochlear implantation is a safe method of hearing rehabilitation in adults.

Bilateral cochlear implantation is an effective treatment for patients with bilateral profound hearing loss. In contrast to children, adults mostly choose a sequential surgery. This study addresses whether simultaneous bilateral CI is associated with higher rates of complications compared to sequential implantation. 169 bilateral CI surgeries were analyzed retrospectively. 34 of the patients were implanted simultaneously (group 1), whereas 135 patients were implanted sequentially (group 2). The duration of surgery, the incidence of minor and major complications and the duration of hospitalization of both groups were compared. In group 1, the total operating room time was significantly shorter. The incidences of minor and major surgical complications showed no statistically significant differences. A fatal non-surgical complication in group 1 was particularly extensively reappraised without evidence of a causal relationship to the chosen mode of care. The duration of hospitalization was 0.7days longer than in unilateral implantation but 2.8days shorter than the combined two hospital stays in group 2. In the synopsis of all considered complications and complication-relevant factors, equivalence of simultaneous and sequential cochlear implantation in adults in terms of safety was found. However, potential side effects related to longer surgical time in simultaneous surgery must be considered individually. Careful patient selection with special consideration to existing comorbidities and preoperative anesthesiologic evaluation is essential.

Preoperative Embolization of Meningiomas Facilitates Reduced Surgical Complications and Improved Clinical Outcomes : AMeta-analysis of Matched Cohort Studies.

The utility of preoperative embolization (PE) of intracranial meningiomas is unclear and controversial. The aim of this study was to investigate the effect of PE on meningioma surgical resection by completing ameta-analysis of matched cohort studies. Asystematic review and meta-analysis of matched cohort studies was completed to evaluate the effect of PE on meningioma resection and outcomes. Outcome measures included: intraoperative blood loss, major surgical complications, total surgical complications including minor ones, total major complications including major surgical and embolization complications, total overall complications, and postoperative functional independence defined as modified Rankin Score (mRS) of 0-2. Pooled odds ratios (OR) were determined via afixed effects model. A total of 6 matched cohort studies were identified with 219 embolized and 215 non-embolized meningiomas. There was no significant difference in intraoperative blood loss between the two groups (P = 0.87); however, the embolization group had asignificantly lower odds ratio of major surgically related complications (OR: 0.37, 95% confidence interval, CI: 0.21-0.67, P = 0.0009, I2 = 0%), but no difference in minor surgical complications (P = 0.86). While there was asignificantly lower odds ratio of total overall surgical and PE-related complications in PE cases (OR: 0.64, CI: 0.41-1.0, P = 0.05, I2 = 66%), there was no difference in total combined major complications between the groups (OR: 0.57, CI: 0.27-1.18, P = 0.13, I2 = 33%). Lastly, PE was associated with ahigher odds ratio of functional independence on postoperative follow-up (OR: 2.3, CI: 1.06-5.02, P = 0.04, I2 = 0%). For certain meningiomas, PE facilitates lower overall complications, lower major surgical complications, and improved functional independence. Further research is required to identify the particular subset of meningiomas that benefit from PE.

Surgical outcome of spinal schwannoma and neurofibroma.

The aim of this study was to evaluate the outcome and surgical complications in patients with spinal schwannoma or neurofibroma surgically treated at the Hospital das Clínicas of the State University of Campinas. This was a retrospective cohort study, using medical records of patients operated between 2011 and 2021. The sample distribution was verified using the Kolmogorov-Smirnov test. The dynamics between qualitative variables were assessed using Fisher's exact test. We used means analysis to assess patient improvement based on Frankel scores. A total of 16 patients were evaluated, of whom 56.25% (9) were men and 43.75% (7) were women. There were 13 (81.25%) patients with schwannomas and 3 (18.75%) with neurofibromas. Patients with deficits had neurological improvement, such as walking or with at least Frankel D or E after surgery. Laminectomy, performed in 8 patients (50%), and laminoplasty, used in 9 patients (56.25%), were the main techniques. The surgical approach was proved to be an effective and safe alternative to the treatment of these tumors, with neurological improvement and minor surgical complications.

Complications and their management in the surgical treatment of Lipohyperplasia dolorosa. English version.

There are both conservative and surgical treatment options for Lipohyperplasia dolorosa (LiDo). Aprocedure that has been established since 1997 is the surgical treatment through Lymphological Liposculpture according to Cornely™. After extensive suctioning of the extremities, an extensive subcutaneous wound cavity with atrabecular connective tissue scaffold remains. Nevertheless, surgery-related complications are rare. Postoperative management and administration of antibiotics and antithrombotics are reviewed. The therapies for complications are presented in detail. Retrospectively, the frequencies of adverse events in 1400 LiDo surgeries in 2020 were evaluated. The mean age of the patients was 47.81years (range 16-78years). Symmetrically, 504 outer legs (outer half of the limb [BO]), 504 inner legs (inner half of the limb [BI]), and 392 arms[A] were surgically treated. Relevant adverse events rarely occurred: infections (1.79%), seromas (0.79%), erysipelas (0.28%), necrosis (0.14%) and deep vein thrombosis (0.07). We were able to reduce the rate of postoperative complications to 3.07% in the Lymphological Liposculpture™ regime for the surgical treatment of LiDo. In their meta-analysis on liposuction, Kanapathy etal. reported an overall incidence of major surgical complications of 3.35%. The overall incidence of minor surgical complications was 11.62%, with seroma (5.51%) being the most common minor complication [26]. Kruppa etal. report that the liposuction procedure including fat removal for esthetic reasons has acomplication rate of 9.5%. Wound infections with 4.5% and the formation of erysipelas with 4% are clearly in the foreground [20].

Risk factors associated with early and late free flap complications in head and neck osseous reconstruction.

This study was designed to identify risk factors for post-operative complications in micro-anastomosed osteomyocutaneous free flaps (MOFF) and analyzed their consequences in long term. A retrospective review of 100 MOFF realized between May 2007 and October 2019 was performed. Demographic data, perioperative management and postoperative complications were enrolled and analyzed in a multivariate model. Patients were followed for ≥ 6months. Major surgical complication rate was 20% with 5% of overall free flap failure rate and 6% of anastomosis salvage surgery. Risk identified for major surgical complication was alcohol consumption (p = 0.0054). Minor surgical complications occurred in 26% of patients mostly due to infections (19%). No significant risk factor was associated to minor surgical complications. Major and minor medical complication rates were, respectively, 10% and 10%. Risk identified for major medical complication were age over 70 (p = 0.0253) and history of chemotherapy (p = 0.0277). Risk identified for minor medical complication were alcohol consumption p = 0.0232) and a history of radiotherapy (p = 0.0329). Alcoholism is an independent risk factor for the surgical complication of MOFF that must be taken into account before surgery. Patients with a history of chemotherapy, radiotherapy or who are over 70years of age are at greater risk of postoperative medical complications and require special attention.

Primary Targeted Muscle Reinnervation after Below-Knee Amputation Is Not Associated with an Increased Risk of Major or Minor Surgical Complications: A Multi-Institutional, Propensity Score-Matched Analysis.

Targeted muscle reinnervation has emerged as a technique to reduce neuroma and phantom limb pain after below-knee amputation; however, the incidence of postoperative complications remains unknown. This multi-institutional study assessed the risk of postoperative complications among patients who underwent targeted muscle reinnervation at the time of below-knee amputation. Patients who underwent below-knee amputation with targeted muscle reinnervation were propensity score-matched 1:3 to patients who underwent below-knee amputation alone. Study outcomes included the incidence of major or minor complications within 60 days. Regression models were used to estimate the relative risk of major and minor complications. Overall, 96 patients were matched, including 31 patients who had below-knee amputation with targeted muscle reinnervation and 65 who had below-knee amputation alone. In the matched sample, a higher incidence of major complications (29 percent versus 24.6 percent), readmission (25.8 percent versus 18.5 percent), and reoperation (19.4 percent versus 10.8 percent) was seen after both procedures compared with below-knee amputation alone. Patients who underwent both procedures displayed a higher incidence of minor complications (25.8 percent versus 20.0 percent), blood transfusion (22.6 percent versus 18.5 percent), and wound healing complications (45.2 percent versus 33.8 percent) and longer operative time (mean ± SD, 188.5 ± 63.6 minutes versus 88 ± 28.2 minutes). There was no statistically significant difference in the risk of major (relative risk, 1.20; 90 percent CI, 0.68, 2.11) or minor (relative risk, 1.21; 90 percent CI, 0.61, 2.41) complications between the two cohorts. Despite an increased incidence of postoperative complications, undergoing below-knee amputation with targeted muscle reinnervation does not confer a statistically significant increased risk of major or minor complications. Future studies are needed to delineate patient selection criteria when assessing the suitability of targeted muscle reinnervation at the time of major limb amputation. Therapeutic, III.

Does Oocyte Retrieval Performance in Mono-follicular Cycles Differ by Physician Experience?

Oocyte pick-up (OPU) is considered as a minor surgical procedure and complications are very rare when performed by trained physicians. However, data on training standards are limited and assessment of proficiency is challenging. The aim of this study was to show the impact of physician experience on OPU performance in mono-follicular in vitro fertilization (IVF) cycles, using two measurable outcome parameters: successful oocyte retrieval and operative time. Senior physicians (n = 6) had over 15years of experience and novice physicians (n = 4) had at least 30 procedures under supervision. The study population included 226 mono-follicular cycles. Oocyte retrieval was successful in 179 out 226 procedures (79.2%); seniors and novices achieved similar oocyte retrieval rates (74.1%, 43/58 vs 80.9%, 136/168, p = 0.270). The mean duration of the procedure was 513.4 ± 163.1 (126-769) s. It was significantly shorter with a mean difference of - 117.9s (95% CI: - 164.4 to - 71.3, p = 0.0001, Hedges g = 1.3) for senior physicians when compared to novices (425.8 ± 146.2 versus 543.7 ± 157.9s). Novices who start performing OPU independently after 30 supervised procedures perform well in collecting the single oocyte grown in mono-follicular cycles; however, the mean duration of the procedure is relatively longer compared to seniors. After initial training period, physicians have few opportunities to compare themselves with their seniors and peers; periodical reassessment of the technique-which should also cover managing the operation time-would help confirm their own practices.

PTERYGOID PLATE IMPLANTS FOR THE REHABILITATION OF THE ATROPHIC POSTERIOR MAXILLA: SURGICAL TECHNIQUE AND REPORT OF CASES.

Introduction: The rehabilitation of the atrophic posterior maxilla with dental implants is a challenging procedure due to various limitations. Low bone quality and quantity, the anatomy of the maxillary sinus and inaccessibility to the area, are the most frequent obstacles that surgeons have to overcome. Several surgical techniques have been used as a solution to this problem, such as sinus lift augmentation procedures with bone graft, guided bone regeneration, tilted implants, short implants, zygomatic implants and pterygoid plate implants. This case report presents the placement of implants in the pterygomaxillary region, aiming to restore the partially edentulous posterior maxilla in two patients, without any additional surgical procedures. The aim was to place a fixed dental prosthesis using a minimum invasive surgical protocol. The usual surgical technique had to be modified because of the anatomical limits encountered in that region, as the quality of bone and the extent of the maxillary sinus. A 30 years follow up is presented. Conclusion: In view of the clinical case follow up and the literature review that only minor surgical complications have been reported, it is concluded that pterygoid implants are a valid and safe solution for the rehabilitation of the edentulous posterior maxilla avoiding more invasive surgical procedures.

Outcomes of clitoral reconstruction in women that experienced genital mutilation and/or genital cutting: 10 years of experience in the Netherlands

BackgroundThe empowerment of women that migrated from Africa and the Middle East to the Netherlands increased the awareness and demand for clitoral reconstruction in women that experienced genital mutilation and/or genital cutting (FGM/C). Our aim was to investigate the outcomes of FGM/C-corrective surgeries conducted over a 10-year period.MethodsWe recruited 72 patients with FGM/C from January 2010 to January 2021. All patients received counseling and underwent strict selection for surgery. Clitoroplasty was performed according to the Foldès technique. Patients were followed for a mean of 13 months. Surgery outcomes were evaluated with a questionnaire.ResultsOf 72 women recruited, 19 (26%) were unsuitable for clitoral reconstructive surgery, due to comorbidities that required prior treatment (n = 5), unrealistic expectations about the surgery outcome (n = 12), a desire for information only about the procedure (n = 2), a choice to treat only a Bartholin cyst (n = 1), or previous surgery for FGM/C (n = 1). As of January 2021, 45 patients had undergone surgery and were included in the present study. After surgery, we performed primary clitoroplasty. Postoperatively, we observed four minor complications. Among all 45 patients, 35 (76%) reported satisfaction with the treatment and improvements in self-respect. Four woman reported disappointment in the aesthetic results, but they were satisfied with the surgery. Six women were lost to follow-up.ConclusionsAfter well-specified preoperative patient selection, clitoral reconstructive surgery led to a high patient satisfaction rate with minor surgical complications. Among patients that desire reconstruction, this surgery can be performed after careful counseling.Level of evidence: Level IV, Risk/Prognostic study.

Risk factors and surgical outcomes of conversion of minimally invasive surgery to open procedure

Background: Majority of laparoscopic procedures can be performed on day-care surgery basis, unexpected conversion to open surgery requires overnight or longer admission in these patients and can have additional financial and psychological impact on the patient. The aim of our study is to study the risk factors associated with conversion and the surgical outcomes in patients who underwent conversion of minimally invasive surgery to open procedure.Methods: It was a prospective observational study. All the patients who were planned for minimally invasive surgery but had intraoperative conversion to open surgeries were included.Results: A total of 41 patients were recruited in the study. Mean age of the patients was 44.7 years. Male patients had more frequent conversion (24 patients, 58.5%). 11 patients (26.8%) had history of previous surgery. Most common cause of conversion to open procedure was dense intra operative adhesions (24 patients, 58.5%); followed by iatrogenic injury to surrounding visceral organs or uncontrolled bleeding (11 patients, 26.8%). The average recovery time (duration till return to work) was 12 days. As per Clavien-Dindo classification, 28 patients (68.29%) had grade I, 9 patients (21.95%) had grade II, 3 (7.31%) had grade III, and one patient (2.43%) had grade IV complication.Conclusions: History of previous surgery and presence of intraoperative adhesions were frequently present in patients who underwent conversion of minimally invasive procedure. These patients required long period for recovery from the surgery and had frequent minor surgical complications.

Racial disparities in short-term outcomes after breast reduction surgery–A National Surgical Quality Improvement Project Analysis with 23,268 patients using Propensity Score Matching

Evidence of widespread disparities in healthcare for racial and ethnic minorities is well documented. This study aims to evaluate differences in surgical outcomes after breast reduction surgery (BRS) according to patients' ethnicities. The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database (2005-2018) was utilized to analyze two propensity score matched patient cohorts-White and non-White-that underwent BRS. Preoperative variables assessed included demographic data and comorbidities such as diabetes mellitus, hypertension, and obesity. Postoperative outcomes assessed were medical complications, minor and major surgical complications, as well as mortality. In total, 23268 patients underwent BRS and met the inclusion criteria. After propensity score matching, the two cohorts were matched with respect to these preoperative variables, and 7187 patients were included in each cohort of White and non-White patients (total 14374). After matching, overall 30-day major complications were not significantly different between White and non-White cohort (2.25% vs 2.14%, p=0.65). After accounting for differences in confounding variables at the patient and socioeconomic level, racial and ethnic minorities who underwent breast reduction were found to experience fewer minor surgical complications. The analysis of temporal trends identified an overall rise in the number of patients seeking BRS, with a higher increase noted in the non-White population. Overall, our findings are reassuring exemptions to prevalent racial and ethnic health inequalities and can serve as a positive example for adequate and fair provision of surgical care.

Carotid endarterectomy; A new center, two years results

Aim: We aimed to evaluate the demographic characteristics and early postoperative complications of patients who underwent conventional carotid endarterectomy (CEA) in a secondary level hospital retrospectively. Material and Methods: Forty-six patients who operated by a single surgeon at Sinop Ataturk State Hospital between January 2015 to December 2016 were included in the current study. Data regarding to demographic characteristics, symptoms, distribution of lesions, diagnostic methods, operation technique and early complications have been collected from handwritten and electronic clinical records. Results: The mean age was found as 70.9±9.7. Thirty patients were male. The most common risk factors were hypertension (93.5%), hyperlipidemia (50%), cigarette (41.3%) and diabetes (34.8%). Conventional CEA (CCEA) was performed to all patients. Patch plasty was applied to only one patient. According to the internal carotid artery stump pressure, T shunt was performed to 17.4% of patients. One patient died in early postoperative period because of myocardial infarction. In four patients; transient dysphagia, in three patients; hematoma requiring revision, in one patient; uncontrolled hypertension, and in one patients wound infection occurred. Furthermore, delirium occurred in one patient. Conclusion: Our experience CEA are compatible with the literature. Our results have supported that CCEA with measurement of carotid arter stump pressure are reliable surgical procedure for patients with carotid artery stenosis. Cardiac complications are rare but it can be mortal. Minor surgical complications are more common than death and stroke risk. However, close follow-up can prevent serious complications.
